IMPROVED RAILWAY-CAR COUPLING.

Specification forming part of Letters Patent No. 95,546, dated October5, 1869.

To all whom it may concern;

Be it known that I, J osEPH O. WILsoN, of Appleton, in the county ofOutagamie and State of Wisconsin, have invented new and usefulImprovements in a Oar-Coupling; and I do declare that the following is atrue and accurate description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,and being a part of this specification, in which- Figure 1 is aperspective view of my device after coupling. Fig. 2 is a side elevationof the same, partially in section, showing the positions of the variousparts before coupling.

Like letters indicate like parts in each figure.

The nature of my invention consists in constructing the ordinarydraw-head and cheeks or filling in the peculiar manner hereinafterdescribed, and fitting a sliding tumbler, which has a curvilinear backand a nearly horizontal shoulder and stop formed on it, to saiddrawhead,in the manner hereinafter specified.

By my invention I am enabled to use the sliding tumbler for holding upthe couplingpin until it is automatically released, in connection withthe ordinary, draw-head after the slight changes in its construction,hereinafter described, have been made' Thus I can at a slight cost applymy invention to draw-heads now commonly used on railroad-cars, whereasin other cases where sliding tumblers have been proposedradical changesin the construction of the draw-head are necessary, and either newdraw-heads are required to be made or very great expense mustbe incurredto adapt the old style to the use of sliding tumblers.

Ain the drawings represents an ordinary draw-head, provided with theusual bellmouthed bumper, B. O are the usual cheeks 0r filling of woodplaced between the upper and lower bars of the draw-head. On the upperside of the draw-head I place a bar or plate, D, made of either wroughtor cast metal, and provided with two slots, to and I), through theformer of which passes the coupling-pin E, which should conform to it inshape. The pin E is prevented from falling down through and out of theslot by a pin, 0, passing through it near its upper end, which stops itat the proper pointin its descent, and to prevent it from beingwithdrawn and lost I attach to its head a chain, d, whose other end issecured to the head of the plate D, and which chain is of butsufficientlength to allow the pin to be raised untilihe shoulder e ofthe dog F can drop under and sustain it. This dog F is curved on therear side, as shown, and works between the cheeks O and in the slot b,through which its head fprojects, and through which passes a pin, g, toarrest its descent through said slot, whileits lower end, when it dropsdown, passes into the slot in the lower bar of the draw-head occupied bythe coupling-pin when it drops to couple. The dog moves against and onan inclined plane, G, which should be of metal, placed between thecheeks O, and, commencing at the back of the slot b, extends downwardand forward to the bottom bar of the draw-head, so that the weight ofthe dog will always cause it to drop into the position shown in Fig. 2when the coupling -pin is raised, when its shoulder 0, coming under theslot a, forms a support for the said pin, which will be thus sustaineduntil the link projecting from the draw-head of another car enters thedraw-head, when it will force the dog up theinclined plane,withdrawingits shoulder from under the coupling-pin, which will thendrop through the link into the slot in the lower bar of the draw-head,when the coupling is effected.

This device is not oply simple in design and operation, but can bereadily applied to the draw-heads of ordinary construction at a verysmall cost.

What I claim as my invention, and desire to secure by Letters Patent,is-

The draw-head A, with its checks or filling O, constructed with theincline G, and having the tumbler F e fitted to it and confined looselyin proper relation to the coupling-pin, so as to operate as set forth,all substantially as do scribed.
